As if it wasn’t obvious that Oliver Thomas Bernsdorff, who went on a killing spree last December, was a mentally ill psycho, the note police have discovered may clinch it.

A Pinellas County teacher who fatally shot his ex-wife, their two children, another woman and himself in December left behind a letter that indicated the killings would cleanse the world of “sociopathic” and “unethical” tendencies, according to newly released documents.

“Though this act may be viewed as depraved and evil, it does, in fact, leave the world a better place,” authorities said Oliver Thomas Bernsdorff wrote in a letter found on his computer after the slayings.

Ballistics tests confirm Bernsdorff used the same gun in all the killings and to take his own life when state troopers tried to pull him over for driving erratically, Clearwater police spokeswoman Elizabeth Daly-Watts wrote in a statement.

Our son found a rotting jellyfish when we were in Florida for spring break, but these girls playing on a beach in Edinburgh, Scotland have him beat — they stumbled upon a woman’s severed head.

A woman whose severed head was found in a bag by children playing on a beach was an attractive brunette who died very recently, police revealed yesterday.

But the European woman, in her twenties or thirties, has still not been identified.

Two sisters aged eight and 11 discovered the head on Tuesday morning at Arbroath, on Scotland’s east coast. A hand was found soon afterwards in the same area, and yesterday police announced a second hand had been found in the same area that evening.

Anyone else a bit creeped out by the head being described as “attractive”?

We’re staunch supporters of separation of church and state, and will go to the mat if we thought our rights were being infringed upon. So when boneheaded teachers and school administrators at a high school in Madison, Wisconsin enacted policies that clearly demonstrate they have no idea what the Establishment Clause really means, they don’t do anyone any favors and just provide more fodder for the other side. See, geniuses, it refers to the government endorsing a particular religion, it doesn’t mean that religious beliefs of the students need to be suppressed or banned. Sheesh, we thought that should be pretty obvious to people with college educations.

According to the lawsuit [filed by the student’s parents], the student’s art teacher asked his class in February to draw landscapes. The student, a [Tomah High School] senior identified in the lawsuit by the initials A.P., added a cross and the words “John 3:16 A sign of love” in his drawing.

His teacher, Julie Millin, asked him to remove the reference to the Bible, saying students were making remarks about it. He refused, and she gave him a zero on the project.

Millin showed the student a policy for the class that prohibited any violence, blood, sexual connotations or religious beliefs in artwork. The lawsuit claims Millin told the boy he had signed away his constitutional rights when he signed the policy at the beginning of the semester.

The boy tore the policy up in front of Millin, who kicked him out of class. Later that day, assistant principal Cale Jackson told the boy his religious expression infringed on other students’ rights.

We’re huge proponents of organ donation, so we’re sure we would have made the same decision as Lisa and Jim Koehne, who donated their 15-year-old son Alex’s liver, pancreas and kidneys after he died from what they thought was bacterial meningitis. So imagine how crushed they must feel after learning their very generous act led to even more heartache:

But it was only after the transplants were performed that autopsy results revealed Alex had a deadly cancer known as anaplastic T-cell lymphoma — not bacterial meningitis.

“We were shellshocked by the whole situation,” Jim Koehne said on “GMA” today. “We had a lot of questions.”

Patient privacy laws prevented the Koehnes from ever meeting the recipients of their son’s organs.

“Two things we did think of [once we learned the truth], one, the recipients, are they OK? Are they all right?” said Lisa Koehne, who added the organ recipients’ doctors had be notified about the situation before she and her husband learned the truth.

“They said they’ll be monitored and looked after,” Jim Koehne said doctors told him.

After the operation, the recipients of the organs all showed evidence of the cancer. The recipient of Alex’s liver underwent three cycles of chemotherapy before finally succumbing to the tumors brought about by the lymphoma. The woman who received Alex’s pancreas initially responded well to treatment but she, too, later died.

Just want to emphasize that we are not placing any blame or fault on the Koehne family.

OK, so this has nothing to do with (human) parenting, but damn if we didn’t need a cute little story as a break from all the child abuse news.

Seeing a dead kangaroo by the highway near her house in southern Australia was nothing new for Leonie Allan and her dog Rex, who were out for a walk on Easter morning.

But back home in their yard in Bells Beach, near Torquay, Rex kept pointing toward where they had seen the roadkill — he is a pointer after all — and eventually took off in that direction.

He came back a few minutes later and dropped a live baby kangaroo at Allan’s feet — a 4 1/2-month-old “joey” he had apparently gone back and rescued from the pouch of its dead mother, according to the Melbourne Herald-Sun.

An 11-year-old boy in Centralia, Washington, was found dead in his home from a gun shot wound. Police believe the gun accidentally discharged while the boy was handling it. We just have to shake our heads at how some parents can be so careless with such deadly items.

Detective Sgt. Stacy Brown said this morning that the handgun involved in the incident had been kept in the house northeast of Centralia, at 724 Teitzel Road, where two brothers were eating dinner in separate rooms.

Although no names have been released as of press time today, Brown said the parents of the children were both working at the time of the shooting and the incident is under investigation. The gun belonged to the father, according to a sheriff’s office press release.

“The kids obviously knew where the guns were kept,” Brown said.

According to Internet address listings, Aaron and Tanya Rothmeyer live at the residence. Based on Lewis County tax lot information, the couple bought the 1920s-era home in April 2001. Brown said multiple firearms were kept there, although she declined to elaborate, citing the active investigation.

Many will certainly recall the case from last November of Megan Meier, who committed suicide after being bullied on MySpace. At the time, Lori Drew — the mother of one of Megan’s former friends — denied being involved with a fake MySpace profile that was set up to lure Megan in and then taunt her. But a former employee of Drew’s is now refuting that claim:

But now Ashley Grills, a 19-year-old employee of Drew’s who created both Evans and the page, claims the mother not only knew about it, but encouraged it. She told a U.S. network the mom called it a “good idea” and alleges she wrote some of the messages that helped lure Meier in.

Grills was the one who found the phony picture they used to represent Evans, a lad who always found an excuse not to meet the shy, overweight teen he befriended and then condemned. And she admits writing the final message that appears to have sent the girl over the edge.

“The world would be a better place without you,” it read. A few hours later, Meier was discovered hanged in her bedroom. But Grills insists she never meant any harm, claiming she was trying to end the online relationship because the hoax had gone too far.

We’re going to be even more thankful for our pleasant, non-psycho neighbors — because while they may mow the lawn a bit too early on a Sunday morning, we don’t think they would ever kill our children. How chilling that this was probably someone they saw every day.

The neighbor of a girl found dead Tuesday night in a bathtub inside his apartment admitted to authorities that he killed her before trying to hide her body, according to Utah police.

Esar Met, 21, lived in a row-house style unit at the same complex where 7-year-old Hser Nay Moo disappeared from Monday afternoon. Met was arrested this morning after he admitted to attempting to hold the child “by force” and she died, according to a Salt Lake County statement. Met also told authorities he tried to conceal the body and other evidence from the crime scene, according to the statement.

Many of us have probably sent our children off to school when we knew deep down that perhaps they might be a wee bit too sick to attend. We’ve even heard from one friend who admitted to dosing her son with an ample amount of ibuprofen hoping to keep his low grade fever down until the final bell rang. We understand when both parents work, and a loss of a day’s wages means a lot when you’re living paycheck to paycheck, but sometimes you have to suck it up and keep the young ones at home — like, say, WHEN THEY ARE INFESTED WITH LICE.

A woman was charged with endangering her children after she sent them to school with lice, despite being warned that they could not attend class.

Nicole Lynn Holmes, 27, was in jail Wednesday and awaiting a preliminary hearing on Friday. Belle Vernon Area School District in Fayette County contacted police, alleging that Holmes was neglecting her two children, according to court records.

The allegations followed several warnings about the children’s lice infestation.
